CLOCK CABINET.

To (IZZ La/Lolli, t may concern.:

Be it known that We, 1V ALTER J. 'Hunsonnen and lVAL'rm: Einnmunr, citizens of the United States of America, and` residents of Cincinnati. in thc county of Hamilton and State of Ohio, have invented a new and useful Improvementv in a Clock Cabinet, of Which the following is a specification.

Heretofore in the manufacture of the cabinets of the type in which the top portion is bent in compound curves, it has been customary to form the top vportion first and thatoperation was vonly accomplished with diiticulty and at a sacrifice of much time.

An object of our invention is to provide a process and apparatus by means of which a cabinet may be formed and assembled at lone operation.

Another object is to provide a device for .arrying out this process that is simple and efficient in its operation.

.Another object is to provide a device of thiskind by means of which a great saving of time 'may be effected.

These and other objects are attained by the means and processdescribed herein and disclosed in the accompanying drawings, in lhlcll Fig. 1 represents a perspective view of a cabinet to be made in a device of our invention. 4

Fig. 2 is a plan vieu of the invention.

Fig. 8 is a `cross sectional .ii-3 ofFig. 2. l

Fig. i is a `cross sectional .JC- 4 of Fig. 2.

Fig. 5 is across-sectional 5-5 of Fig. 6.

Fig. 6 is a view taken on line 6-6 of-Fig. 3 and showing a cross-sectional view of the stationary mold only.

For example let it be supposed that a .clock cabinet shown in Fig. 1 is to be made.

T he clock cabinet 6 comprises a -fa-ce 7, a Vbach 8, sides 9 and -t'op 10. vThe top 10 comprises a number oflayers or laminations 11 ofveneer. 'The device comprises a're ctangul'ar 'base 12 Which may beconstructed of angle ifron'or channel lironsandsupported upon suitable uprights 13. Mounted on `top of Vthe base is a pair of relatively movable molds, the -first o r ixed mold 14, is substan- 'jtially T-shaped, the end 15 of the stem 16 device of the view on line view on line view on line Vgrooves 24 of the mold 21.

being formed to conform with the inside central portion of the top 10 of the clock cabinet. The sides 17 of the stem 16 carry dove-tailed grooves 18. Complementary slidable .sections 19 carry upon their iat sides suitable dove-tailed slides 20 Which engage in the dove-tailed grooves 18 of the stem as is shown in Fig. 5. The Sections 19 when slidably fitted upon the stem 16 conform to the inner curved portion of the cabinet ti which may be substantially cylindrical as is shown in jFig. 1 or of any other desired shape. T he second or movable mold 21 and its adjustable ymembers or molds 22, are capable of adjustment to conform with the outer contour of the cabinet 6. The movable mold 21 has diagonal faces 23 eX- tending from the central opening thereof, the sides 2/-1 of which are provided with dove-tailed grooves 25. The adjustable members 22 are provided with dove-tailed slides 26 which engage in the dove-tailed A suitable "adjusting screw 27 is mounted in a threaded bore in a frame of the mold 21 and its one end is sivivel mounted to the adjustable mold The-other end of the screv7 27 is provided ivithasuitable actuating 'handle or crank .28. The movable 1nold-21 carrying adjustable molds 22 is slidabl-y actuated as a unit lby means :of a jack screw 29, the threads of lwhich engage in a threaded bore of a block 30 mountedfat the end of the frame l12. The end of the scre'WQQ is swivel mounted at 32 to the-mold 21. A hand Wheel or lever 8l is secured to the screw 29 wherebythe mold 21 may be moved into and out of engagement with mold 14. The movable mold and tits adj ustablewmembers 22 have chambers 33 and 34 therein and these chambers are connected with kone another wtlrsuitablelexible ,hose Vor pipes 3G. Suitable ports 37 and ,38 are'located at the extreme sides ofthe Amjold 2l land a valve A370 is `provided' whereby a suitable heating medium suoli as hot vWater-may .be admitted ,to `the vchambers {33 and 3,4 and exhausted therefrom.' A .suitable cooling medium is arranged to vbe likew-ise' fad# yi'nitted `to'and exhausted `from these chami bers `through the .same port-s. 'The fixed mold has `bores 89 through the upper portions `of its extreme upper side through which extend ejectors or ejector pins 4;() actuated by levers -ill hingedly mounted to the outer side of the ized mold le. rl`he purpose oi these ejectors is to remove work trom the mold after completion. A loose bar lo olf any suitable material. is inserted between the mold le and the portion ot the work and is adapted to be engaged by the pins l0 when they are employed to separate the work from the mold llt. The purpose ot' the bar e6 is to preclude damaging the cabinet. A suitable clamp #l2 is mounted above the top ot mold ll and carries a lianged disc -lwhich may be brought into contact with the portion T ot the work by any suitable means such as a hand screw dei threadedly mounted in the clamp l2. The purpose of the clamp and disc is t'o prevent the work trom warping while in the mold. The work is supported at the bottom with suitable cross bars l5.

As a summary, the apparatus oi the inve tion consists in a pair ot relatively movable composite molds each having` relatively movable sections associated therewith. The first mold with its complementary sections 19 corresponds to the interior oit the cabinet to be made, while the second mold and its adjustable molds 22 are adapted to conform to the outer shape of the cabinet.

The process oi' making, the cabinets and operation oi the mold is as follows. Comw plementary sections 19 are slidably mounted upon the rst `or fixed .mold 1.4.-. The wood to be used in making the cabinet is cut to dimension and placed in position. in the mold., having previously had its joints coat-- ed with glue. The several lay of veneer 'll are coated with glue and placed eentrallv in position against the rounded portion lo of the first mold. rlfhe second mold 2l having its adjustable sections @n drawn .f /J baclr within the lines of its curved surface, is then brought forward so as to hold the layers l1 of the top l0 between the two molds. The other component portions ot the cabinet, namely sides Y and 8 and ends 9 are then properly positioned and the 'disc i3 inserted into the tace opening ot the front 6 ol the cabinet. These part-s having been positioned, the adjustable molds Q2 are then screwed into place, the entire cabinet then being tightly clamped on all sides. A heating liuid such as hot water is then admitted into the chambers after which the molds may be tightened somewhat. ift-iter the mold and the worlr therein has been suiiicientlj7 heated a cooling medium such as cold water is then admitted in the saine manner as was the heating medium, whereupon the glue or bonding substance will be chilled and set. The second mold 21 is then with drawn .and carries with it the cabinet. The .ejector pins A.and levers l0 and Lll beingused to loosen the work from the lit-st mold lil, the sections `ot :the tiret `mold Awill be with essere? drawn therefrom by the cabinet as it is withdrawn and may then be easily removed from the cabinet and replaced upon the iirst mold for making another cabinet, lt will be readily noted that the device need not le confined to making only the type oi cabinet shown, but with such modilications as are well within the skill ot an ordinary mechanic, may be used for making various types oit cabinet work. 'llhe process and method just described requires about l5 or Q0 minutes oit time to assemble a cabinet, while by the older method live or six hours olE time was required to torni the top alone.

Another advantage attained by the method and device described, is that the work accomplished is uniform and more accurate than that made by the old method, because the joints are more firmly and venly united and the parts are not subject to the distortions incident to piece-meal construction ot the cabinet.

lflhat we claim is:
